What is Your Bankai?

Quick note for those of you who do not know what a bankai is; it is basically an ultimate form of a sword. It's in the anime Bleach, an anime I heavily suggest everyone to look in to! Back to the question at hand; what do you feel is your bankai?! Is it, elegant and graceful as Byakuya's; fiery and destructive as Yamamoto's; or subtle but powerful as Ichigo's? Your pick!
I feel mine is fierce and monstrous as Toshiro's!

It may look like it, but this is not a Pokemon. It's a sword!
